Frequently asked questions

What is URL encoding?

URL (percent) encoding replaces characters that are unsafe in URLs — like spaces and &, ?, = — with %XX codes so they travel safely in links and query strings.

What characters get encoded?

This tool encodes a URL component, so reserved and non-ASCII characters are escaped. Letters, digits and a few safe symbols (- _ . ! ~ * ' ( )) are left as-is.

Why did decoding throw an error?

Malformed percent sequences (an incomplete % code) cannot be decoded. Check that every % is followed by two hex digits.
